Yes. I got the mail. Checked it now. I am fine with the rep lost :) actually, but I do want to know what action (as in which question) caused this.

@Down: I know I flagged for rep re-calc :D. But, since I didn't check my mail, I wasn't sure if it was recalc by moderator or some unicorn :).

@nvl Unfortunately I'm not sure if we're able to say specifically which questions/answers caused the changes in rep.

@nvl a rep loss on a recalc can have any number of reasons, e.g. answers you gave to questions that were deleted later, that received upvotes, a question you deleted etc. etc.

Can't there be an automated system detailing what caused the rep change (plus/minus) and sent as email to user. That would at least reduce the number of rep questions on Meta :)
